In this research, we propose a noble methodology for modeling and simulation of the intensity and direction of the magnetic fields generated by coils in a limited 3-dimensional region. This method was strictly based on the Biot-Savart's law determining the magnetic fields induced by currents flowing through the coils. We also used Finite Element Method (FEM), a numerical technique for finding a solution for each subdivision of a whole domain within the regions of interest. Based on the introduction of rotational transform method for an arbitrary axis, this method possesses a strong analysis capability for the magnetic fields in the vicinity of the coil at an arbitrary position in 3-dimensional region. In addition, a linear calculation system adopted in the simulation process was able to carry on high-performance analysis for the magnetic fields generated by even multiple coils. We strongly propose that this noble method would be a powerful simulation tool for the design of a system that can generate magnetic fields within a 3-dim region of interest considering both the intensity and direction.

Remote-control technology is required in an unmanned vehicle such that it can replace humans for executing tasks in various extreme environments. In particular, a remote scene must be reconstructed using 3D meshes for enabling a user to remotely control an unmanned vehicle easily and intuitively. To this end, a large amount of multiple sensor data would be processed using various algorithms in real time. Considering the limited hardware specifications in extreme environments, it is difficult to implement 3D terrain reconstruction in high-quality and real time. This paper proposes the optimization of the architecture of a multiple-sensor-data pipeline. The improved performance resulting from the optimized architecture was analyzed through experimental comparison with a non-optimized system.

In this study, we propose a measurement system consists of two pairs of multiple cameras mounted on a pan-tilt unit and a landmark installed on a target side. The purpose of the proposed system is to measure relative position and heading angle of a vessel to a target at a close distance, in order to reduce collision risks by automation of vessel positioning that requires high measurement accuracy and rate. To achieve such measurement, cameras that have wide sensing range and high angular resolution are used instead of GPS, radars, or laser sensors. The proposed system also has the ability of accurate and fast measurement of the distance and direction angle to a target by applying a simple and robust target detection method. The position and heading of a vessel are determined from two pairs of the distance and direction angle. To evaluate the measurement accuracy of the proposed system, we measured position and heading of the system relative to landmarks on several conditions including positional displacement and rotation. The experimental results demonstrate that the proposed system can be used for automation of vessel positioning at a close distance.

When 3d image registration using 2d image by hand-held scanner, the most important thing is pose estimation and object surface measure. The relationship between images is important to image registration. In this paper suggest 3d registration using Kinect and INS. The Kinect and INS are integrated on rigid body to improve the accuracy of estimate pose. It can complement the disadvantages of each sensor through the sensor fusion of INS and vision sensor position to make more precise estimates. Using purposed system can measure the three-dimensional shape of a variety of objects, and also can obtain an accurate image in a medical imaging applications which require precision application and apply in Image-guided surgery.

Monitoring system has become one of the most important means for perimeter intrusion prevention. But most of existing monitoring systems are passive surveillance. In this paper, we propose a method to implement active perimeter intrusion detection by identifying human targets in video images captured by monitoring system. In order to enhance the robustness of detecting postures of human targets, this paper introduces Fourier Descriptor (FD) and Histogram of Oriented Gradients (HOG) to realize an effective detection of human bodies with multiple postures captured by fixed cameras. The experiment results confirm that the proposed algorithm has higher recognition rate for detecting human targets with walking, climbing, and jumping postures, and sufficiently meets the requirements of perimeter intrusion detection.

In this paper, a dance rehabilitation system using Kinect and a vibration feedback glove is proposed. The proposed system provides enjoyable and fun rehabilitation treatment by combining a markerless motion capture system, vibration feedback, and dance music. This system shows a sequence of arrows which are generated by dance music, and the patient is required to touch the arrows in appropriate timing. The patient's own motion is captured by Kinect, and provided to the patient in real-time as visual feedback. Also, the glove applies vibration feedback as he/she touches the arrows. The patient's movements are recorded and analyzed for improved rehabilitation program.

This paper presents improved robotic mechanism for automated biopsy procedure. Needle insertion type intervention has the advantages of minimal invasiveness and fast recovery of the patient, but radiation exposure of the clinician and patient and dependency of insertion accuracy on the clinician's skill are drawbacks. The robotic intervention system is a solution of the problems. As one component of the system, the robotic mechanism for biopsy has been developed. The previous robot mechanism sequentially performs all the processes of the biopsy except the anesthesia, but more practical problems such as robust operation, necessity of down-scaling, and safety issue should be considered. The biopsy robot model II-B is the revised version of the previous models. The modifications include adding a cartridge rotation checker and needle stoppers, renovating cartridge connection method, the spring loader, and spring block mover, and etc. Effectiveness of the improved functions is verified by experiment.

In this paper, we developed and tested comparison performance of our developed Integrated Cathodic Protection Monitor (ICPM) with other instruments. ICPM is more accurate than other products due to using high impedances(100MO) to fit high soil specific resistances. And we achieved measuring of corrosion protection voltages at the fields and comparing of those data with other instruments. We demonstrated our ICPM more excellent than other products through experiments.

A new methodology is presented for the stability problem of genetic networks with time-varying delay in the current article. Novel stability criteria with delay dependency in terms of linear matrix inequalities for gene regulatory nets are derived by the proposed augmented Lyapunov-Krasovski (L-K) functional. Our proof deployment applies the technique of second order convex combination, and the property of quadratic convex function without resort to Jensen's inequality.
